Green light in the middle of the screen

Well, if Apple technicians diagnose that it is a manufacturer's defect AND your iPhone X is still covered by warranty, it will be repaired/replaced without charge.

But we, just users like you, can't judge about those problems.

Giulio is right.

I wanna add, if you're referring to

https://support.apple.com/iphone-x-display-module-replacement-program

> that is about ghost touch, touch issues. But even in those cases, the device needs to be inspected for diagnostic purposes.

It looks like a screen failure, but we can't diagnose that kind of issue remotely, sorry.

Please contact Apple Support (they have tools to run remote diagnostics):--> Get Support
